CARL M. BOLL, OF MERRILL, WISCONSIN.

LOG-BUOY.

To all whom it may concern:

Be it known that I, CARL M. BoLL, a citizen of the United States,residing at Merrill, county of Lincoln, and State of Visconsin, haveinvented new and useful Improvements in Log-Buoys, of which thefollowing is a specification.

My invention relates to improvements in log-buoys or floats.

The object of my invention is to provide a simple and e'flicient floator buoy, which is adapted to be quickly and easily attached to heavylogs or timber, the specific gravity of which is such that they will nototherwise float in water.

My invention pertains more specially to the mechanism by which a floatmay be quickly and easily attached to the upper surface of a log at aslight distance from its respective ends, whereby the liability of thesame being broken or detached by contact with other logs or stationaryobjects is avoided and whereby when the log has been transported to amill or market, the buoy maybe quickly removed therefrom and again andrepeatedly used for like purposes.

My invention is further explained by ref erence to the accompanyingdrawings in which,

Figure 1 represents a side view of my device in connection with asubmerged log. Fig. 2 represents an end view of the device, shown inFig. 1. Fig. 3 is an enlarged de tail drawing of the fastening dogremoved from the log, showing lug 10 curved upwardly instead ofdownwardly. Fig. el represents amodified form of fastening device, inwhich the dog is connected with the float through a slidable instead ofa pivotal connection, and Fig. 5 represents the dog inserted through anaperture of a rigidly con nected bar.

1 represents a log submerged in water, 2 represents the buoy by whichthe log is caused to float in the water, the buoy 2 being preferablyprovided at its respective ends with fastening lugs 3, which are securedthereto by bolts or ri 'ets i, in any convenient manner.

5 is a fastening dog, which is. pivotally connected with the lugs 3 bythe pivotal bolt 6. The dog 5 is provided with a fastening barb. 7,which is adapted to be driven into the surface of the log, whereby thefioat Specification of Letters Patent.

is securely held in place. The dog also comprises an impact head 8,which is adapted to receive the strokes of a mallet or hammer whendriving the barb 7 into the surface of the log. The dog 5 is alsopreferably provided. 'ith an elongated slot 9 for the reception of thepivotal bolt (3, which permits of the required movement between thepivotally connected parts which is produced as the barb is being driveninto the log. The dog is also preferably provided with a rearwardlyprojecting lug 10, which facilitates in disengaging the barb from thelog and between which and the log a crow bar may be inserted for suchpurposes. The float 2 is preferably made of sheet metal but may be madeof wood or other substances of less specific gravity than water.

In the modified form, shown in Fig. 4-, the float 2 is provided at itsrespective ends with an elongated loop 12, while the dog is pro videdwith a lateral projection 13 through which an aperture l i is formed,for the reception of said loop 12. whereby when the barb T is driveninto the log, said lateral projection 13 is free to slide down upon saidloop until the barb has penetrated the required distance into the log.It will be understood that in other respects, the modified form isadapted to perform the same functions as the dog shown in the otherfigures.

In the modified form shown in Fig. 5, a horizontal bar 15 is connectedwith the float ing dog 18. The dog 18 is provided with an aperture 17for the reception of a fastening dog 18. The dog 18 is provided withlaterally projecting lugs 19 and is connected with the float by a chain20.

Havii'ig thus described my invention what I claim as new and desire tosecure by Letters Patent is,

1. The combination of an elongated float adapted to be secured at itsrespective ends to the sides of a log, fastening dogs movably connectedwith the respective ends of said float, respectively provided with abarb and a contact head against which the strokes of a hammer may beapplied for forcing said barb into the log.

2. The combination of a cylindrical float, a fastening dog movablyconnected with the respective ends of said float, provided with a barb,a head against which the strokes of a hammer may be applied for forcingthe gaging said dog from a log and means for movably connecting saiddogs With the respective ends of said float.

In testimony whereof I atfix my signature in the presence of twoWitnesses.
